I thought that technical conferences and talks could be a possible way for us to improve. Unfortunately we can't afford to invite people to talk before our team on a regular basis as Google does.

So the idea was to take advantage of the internet and the kindness of people who had shared their talks or lectures online, and, at least, watch them on video. It surely was not like the real thing, but still it was better than nothing. After each talk, if there was time, we could debate about what we had seen.

So I commented it to a work colleague and we asked our boss if we could do it.
He agreed and this way we started the PELE Developers Tech Talks.

These talks are meant to be an informal way of learning about technology and best practices that might be relevant to our project.

Then modify the following lines in /var/lib/pgsql/data/pg_hba.conf (the initial lines remain in the file but commented)

# "local" is for Unix domain socket connections only
#local all all ident local all all md5
# IPv4 local connections:
#host all all 127.0.0.1/32 ident host all all 127.0.0.1/32 md5
# IPv6 local connections:
#host all all ::1/128 ident host all all ::1/128 md5

After saving the changes in pg_hba.conf, restart the server for them to take effect.

Verify that adminpack is working.
Launch pgAdmin3 and connect to the Postgres server you just installed adminpack on. Once connected to the PSQL server click Tools in the top navigation menu, select Server Configuration from the drop down, and then select either pg_hba.conf or postgresql.conf to view a configuration file. You shouldn't get any error. With the adminpack contribution installed you will now be able to edit pg_hba.conf and postgresql.conf configuration files directly from pgAdmin3.
